LUBRICATING SYSTEM.

Application filed May 31, 1913.

To all whom it may concern:

Be it known that I, Gnoncn R. WADs- WORTH, a citizen of the UnitedStates, residing at Cleveland, in the county of Guyahoga and State ofOhio, have invented a certain new and useful Improvement in LubricatingSystems, of which the following is a full, clear, and exact description.

This invention relates to lubricating systems adapted particularly foruse in con nection with internal combustion engines. The object of theinvention is to provide in a lubricating system of the forced feed typeemploying a pump which normally forces oil to the bearings, asupplemental source of supply so arranged with respect to and connected.to the passageways leading to the bearings that oil may be fed to thebearings by gravity, so that the bearings may be lubricated with gravityfeed, in case the pump gets out of order, or does not worksatisfactorily. I

In carrying out my invention, the pump which is normally employed toforce oil to the bearings and which may be located in the bottom of thecrankcase of the engine, is connected to a manifold from which the oilflows to the various bearings which are adapted to be supplied with oil,and in connection with this system, I provide a tank which may have apipe connection with the manifold so as to supply oil thereto in casethe pump is out of order. A suitable valve may be provided between themanifold and the tank so as to control the passage of oil from the tankto the manifold, and a valve may be provided between the manifold andthe pump, so that communication between the pump and manifold can beclosed when the oil is to be fed by gravity from the auxiliary source ofsupply.

In the drawings, the single figure shows in a simplified form a portionof the inter nal combustion engine equipped with my improved lubricatingsystem.

I have omitted from the drawing, the major portion of the engine, andhave shown only such parts as are required to be shown for a clearunderstanding of the invention. The parts of the engine Which are shown,include a crank shaft 10 and a bottom portion of the crank case 11. vTheoil is normally forced to the crank shaft bearings which are to belubricated by a pump 12 which in this case includes two intermeshingSpecification of Letters Patent.

oil feeding gears 1:2, one of which is adapted to be positively drivenby shaft 12 which may be connected to the engine in any suitable manner.This pump is preferably located in a pit or reservoir 13 in the bottomof the crank case 11. The outlet side of the pump is connected by asuitable passageway 1 1 to a manifold 15 to which the oil is adapted tobe forced or fed by the pump 12. This passageway between the manifoldand pump may be closed by a suitable valve 16, which, however, isnormally open. The manifold which is below the crank shaft 10 isconnected to the bearings of the latter by suitable passageways 17through which oil may be forced by the pump.

Ordinarily the parts so far described will be sufficient to oil all thebearings which need be supplied with oil, the oil being forced up to thebearings and then permitted to drain back. into the pit or reservoir ofthe crank case in the usual and well known manner. In carrying out myinvention, I utilize, in connection with the forced feed oiling systemabove described, an auxiliary source of oil supply 18 which is to beutilized in case the pump is out of order or is not workingsatisfactorily to supply a suflicient amount of oil to the bearings. Thecapacity of this tank will be such that it normally contains asuflicient amount of oil to lubricate the bearings for a run of a fewmiles, or for a sufficient length of time to enable the operator toreach a point at which the pump can be repaired, so that oil can be feelor supplied in the normal manner, and by the normal means.

The tank 18 is provided with an outlet pipe 19 which is normally closedby a threeway valve 20, the chamber of which is con' nected to themanifold 15 and to a pipe 21 leading to the reservoir 13. When the valve.is in the position shown in the drawing, bil

does not flow from the tank either into the manifold or into the pipe21. In case the valve is moved from the position shown,

the pipe 19 is connected to the pipe 21, and

oil flows into the reservoir. In case the valve is moved 180 from theposition shown, oil flows from the tank into the manifold, the tank issufficiently elevated with respect to the manifold and bearings to beoiled that when the tank is connected to the manifold, 01' will not onlyflow by gravity from the 01 into the manifold,

bricated, a pump having its discharge side 15 connected. to themanifold, a storage receptacle supported above the manifold, aconnection between the receptacle, the manifold and inlet side of thepump and valvular means controlling the connection between thereceptacle, and the manifold or the pump.

In testimony whereof, I hereunto afiix my signature in the presence oftwo witnesses. GEORGE R. WADSlVORTH. Witnesses L. I. PORTER,
